Clos Du Val Winery is a winery in the Stags Leap District of California's Napa Valley. The winery was founded by two men who were born into the French wine business, John Goelet and Bernard Portet. After scouting the World for two years to locate areas where they might produce Bordeaux-style wine, Porter identified the then-undiscovered Stag’s Leap district of California’s Napa Valley as especially promising. Goelet bought 150 acres (61 ha) of vineyard land and established the winery in 1972. The next year he bought 180 acres (73 ha) in the Los Carneros region to produce the Burgundian varieties, Pinot Noir and Chardonnay.
The winery received international recognition when its first vintage of Cabernet Sauvignon (1972) achieved eighth place in the Judgment of Paris. In the French Culinary Institute Wine Tasting of 1986, Clos Du Val Winery won first place. In The Judgment of Paris 30th Anniversary the judges awarded Clos Du Val fifth place.
